Method for preparing high-strength silicon oxide ceramic through photocuring 3D printing

The invention discloses a method for preparing high-strength silicon oxide ceramic through photocuring 3D printing. The method comprises the following steps that 1, silicon oxide ceramic printing slurry is prepared; step 2, biscuit forming; and step 3, degreasing-sintering treatment. The method solves the problem that a traditional method is difficult to prepare a complex fine structure, the forming precision of the silicon oxide ceramic is improved, the preparation period of the silicon oxide ceramic is shortened, and the problems that existing silicon oxide ceramic prepared through 3D printing is prone to layering and low in strength are solved; the interlayer bonding force of the silicon oxide ceramic is large, and the interlayer bonding strength and the overall strength are improved; the bending strength is high; and the comprehensive technical effect is excellent. 一种光固化3D打印制备高强度氧化硅陶瓷的方法，其包括以下步骤：步骤1，氧化硅陶瓷打印浆料制备；步骤2，素坯成型；步骤3，脱脂-烧结处理。本发明解决了传统方法制备复杂精细结构困难的问题，提高了氧化硅陶瓷的成型精度，缩短了氧化硅陶瓷的制备周期，解决了现存3D打印制备氧化硅陶瓷易分层、强度
